Operation
Note:
1. In the ‘Register’ column, except for the Receive/Transmit Multiplexed mode, the register position of Framer 1 is listed to represent the set of the registers of eight framers. The other reg-
isters positions are tabulated in the ‘Register Map’. However, in the Receive/Transmit Multiplexed mode, the registers positions of the eight framers are all listed.
2. The ‘Description’ illustrates the fundamental function of the operation mode. The others can be configured as desired.
